3. Terms and definitions
List of radiation diseases
3.1 Radiation induced diseases A general term for injuries or diseases caused by ionizing radiation. 3.2 Occupational exposure All exposures to which workers are exposed in the course of their work, except for exposures excluded by national laws and regulations and standards, and exposures produced by practices or sources that have been exempted according to regulations. 3.3 Radiation worker Workers engaged in radiation work, also known as occupationally exposed persons or radiation workers. 3.4 Emergency exposure
Emergency exposure
A type of abnormal exposure, refers to organized and voluntary exposure at the time of or after an accident in order to rescue people in distress, prevent the situation from escalating, or other emergency situations. Individual monitoring
3.5 Personal detection
Measurement using a dosimeter worn by a worker, or measurement of the type and activity of radionuclides in their body and excreta.
3.6 Personal dosimeterPersonaldosimeter An instrument worn by radiation workers to determine the absorbed dose and dose equivalent value received by individuals. Biological dosimeterBiologicaldosimeter3.7
A biological system used to estimate the irradiated dose. There is a quantitative relationship between the reaction of this biological system after irradiation and the irradiated dose, which can be used to estimate the irradiated dose. J Area monitoring
3.8 Workplace monitoring
GBZ112-2002
Monitoring to provide workers with data on the working environment and radiation levels related to the operations they perform. 3.9 Biological sample analysis Biological sample analysis is an analysis of biological materials aimed at determining the presence and quantity of radioactive materials accumulated in the body. 3.10 Late radiation effect Late radiation effect is a harmful effect that occurs in the long term after a single exposure to a large dose or multiple exposures to smaller doses. Generally refers to effects that occur several years after exposure, such as leukemia and related cancers. 3.11 Medical follow-up observation Medical follow-up observation is a long-term systematic medical observation of abnormally exposed persons or persons suspected of having health changes due to radiation, with the purpose of discovering the long-term effects of radiation. 4. Principles for the diagnosis of occupational radiation diseases 4.1 There must be a history of occupational or emergency exposure. 4.2 The exposure dose data must come from the personal dosimeter they wear and the personal and site dose monitoring files. If necessary, reliable dose reconstruction data can be referred to. The cumulative exposure dose must be close to or reach the dose threshold given in the diagnostic standards for various radiation diseases, especially for radiation diseases with deterministic effects. 4.3 The diagnosis must be based on the exposure dose (including dose rate), clinical manifestations, and laboratory test results: refer to the previous health status; and exclude other factors or diseases, and make a comprehensive analysis before making a diagnosis. 4.4 The diagnosis of occupational radiation diseases must be based on its corresponding "diagnostic criteria and treatment principles". 5. Basis for diagnosis of occupational radiation diseases 5.1 Collect information on occupational health examination results, occupational exposure history and overexposure. The unit where the individual is located and/or the relevant radiation protection department must provide the following information and data signed by the legal representative: 5.1.1 Occupational exposure history;
5.1.2 Occupational health examination results and occupational health files (copies): 5.1.3 Personal and/or site dose monitoring history records; 5.1.4 Exposure conditions and personal and site dose monitoring results during exposure. 5.2 Results that can be used as biological dosimeters for exposed persons, such as lymphocyte chromosome aberration rate, micronucleus rate, blood test results, etc., as well as biological dose data calculated based on this; and analysis results of biological samples of exposed persons. 5.3 Detailed clinical manifestations, laboratory test results and special laboratory test results related to radiation effects; 5.4 Other possible causes or diseases need to be excluded, and the basis for exclusion should be listed. 6. Requirements for occupational radiation disease diagnosis institutions 6.1 Occupational radiation disease diagnosis should be undertaken by medical and health institutions approved by the health administrative departments of the people's governments at or above the provincial level. 4
6.2 Medical and health institutions engaged in the diagnosis of occupational radiation diseases should meet the following conditions: 6.2.1 Hold a "medical institution practice license" 6.2.2 Qualifications for assessing the radiation dose of exposed persons: 6.2.3 Have professional physicians who have graduated or trained in radiation medicine; 6.2.4 Have radiation cytogenetics testing equipment and the ability to estimate the dose of exposed persons using biological methods; 6.2.5 Have the ability to comprehensively analyze and assess the radiation dose of exposed persons; 6.2.6 Have a sound occupational disease diagnosis quality management system. 6.3 Professional physicians engaged in the diagnosis of radiation diseases must have the following qualifications: 6.3.1 Graduated from or trained in radiation medicine and have a technical title of intermediate level or above; 6.3.2 Familiar with and master the professional knowledge of radiation dosimetry and radiation protection; 6.3.3 Familiar with and master the diagnostic standards and treatment principles of occupational radiation diseases; 6.3.4 Have more than 5 years of clinical practice in radiation diseases. 7. Principles of treatment of occupational radiation diseases
GBZ112-2002
7.1 Timely and correct on-site rescue, especially for life-threatening injuries, to save lives with all efforts. Remove the exposed person from the radiation source as soon as possible, wash away the radioactive contamination, and take measures to block the absorption of radionuclides. 7.2 Collect the data that can be obtained on site as soon as possible for measuring or evaluating the dose of the exposed person: such as site monitoring data; items that can be used to infer the dose of the exposed person and biological samples that can be used as biological dosimeters to estimate the dose. 7.3 Take possible comprehensive symptomatic treatment and supportive therapy in a timely manner to improve the body immunity of the exposed person. 7.4 Comprehensively analyze the exposure situation and use the dose data collected from various aspects to evaluate the dose of the exposed person, determine the condition, and take effective treatment measures.
7.5 Provide timely explanations to the exposed person and his family, and maintain good communication with the management department and the media. 8 Supplementary Provisions
8.1 Medical and health institutions that undertake the diagnosis of occupational radiation diseases should establish radiation disease diagnosis files and keep them permanently. 8.2 Medical and health institutions should promptly report the occupational radiation diseases they diagnose to the relevant departments for filing. 8.3 Patients with occupational radiation diseases should be included in the medical follow-up observation plan.
